| 摘 要： | 目的探讨颈动脉三维对比增强磁共振血管成像(3D CE-MRA)技术的规范。方法回顾性分析20例患者颈动脉3D CE-MRA的参数设置、实际操作和图像质量。结果不同对比剂注射方法、扫描方式、对比剂速率,以及是否使用生理盐水对图像质量的影响有显著差异。结论运用高压注射器注射对比剂、采用透视触发技术(主动脉弓显影至最亮时启动扫描)、维持对比剂速率2.0~3.0 mL/s、使用生理盐水维持团注,可提高3D CE-MRA的图像质量。

| Abstract: | Objective To explore the standardization of carotid three dimensional contrast enhanced magnetic resonance angiography(3D CE-MRA) technology.Methods The parameter setting,actual operation and image quality of 20 patients with carotid artery 3D CE-MRA were retrospectively analyzed.Results The image quality was affected significantly by different injection methods of contrast agent,scanning mode,injection speed of contrast agent and use or not use of physiological saline.Conclusion Application of high pressure injector and perspective trigger technology(start scanning when the aortic arch developing to the brightest),maintenance of injection speed within 2.0～3.0 mL/s and maintaining group injection by normal saline can improve the image quality of 3D CE-MRA. |
